Audio-Technica AT8461a Lavalier Microphone Clip Set

The AT8461a is the mounting hardware for Audio-Technica's BP898 and BP899 subminiature lavaliers, supplied three to a pack in black. Each set gives you a clothing clip base plus two interchangeable holders: a single holder for one capsule and a double holder for running a backup mic alongside the primary.

Stocking a pack of these is what keeps a lavalier kit working through a shoot day. Clips get bent, lost in wardrobe changes, and handed off between talent, and a spare double holder is also the cheapest way to add redundancy to an interview position without buying a second transmitter.
